Purification is based on magnetic beads as the separation matrix. Norgen s magnetic beads bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. The genomic DNA is preferentially purified from other cellular proteinaceous components. Typical yields of genomic DNA will vary depending on the cell density of the blood sample. The purified genomic DNA is fully digestible with all restriction enzymes tested, and is completely compatible with downstream applications including real-time PCR, NGS and microarray analysis. Norgen s Blood DNA Isolation 96-Well Kit (Magnetic Bead System) also can be integrated with a robotic automation system. Norgen s Purification Technology Purification is based on the use of magnetic beads that bind DNA under optimized binding conditions. Norgen s Blood DNA Isolation 96-Well Kit (Magnetic Bead System) allows for the isolation of genomic DNA from various different blood samples, including human. Lysis Buffer B and Proteinase K are added to the sample, mixed and incubated at 55 C to lyse the cells. Ethanol is then added to the lystate, and it is then transferred into a well of the 96-well plate. Magnetic Bead Suspension is added to the clean supernatant, and the resulting solution is placed on the magnetic separation rack. Only the DNA will bind to the magnetic beads, while most of the proteins will be removed in the supernatant. The bound DNA is then washed with Solution WN and 70% ethanol in order to remove any remaining impurities and the purified total DNA is eluted with the Elution Buffer B. The purified DNA can be used in a number of downstream applications.

Procedure Notes prior to use: Ensure that all solutions are at room temperature prior to use, and that no precipitates have formed. If necessary, warm the solutions and mix well until the solutions become clear again. Always vortex the Magnetic Bead Suspension before use. Always vortex the Proteinase K before use. Preheat the incubator(s) according to the protocol (37ºC, 55 C or 65 C).Prepare a working concentration of the Solution WN by adding 73 ml of 96-100 % ethanol (provided by the user) to the supplied bottle containing the concentrated Solution WN. This will give a final volume of 128 ml. The label on the bottle has a box that may be checked to indicate that the ethanol has been added. For best results, the use of whole blood collected into tubes containing an anticoagulant is highly recommended. Both fresh and frozen anticoagulated blood may be used with this procedure. Ensure that frozen blood is thawed at room temperature prior to starting the protocol. For blood containing Gram positive bacterial pathogens, prepare a 400 mg/ml stock solution (approximately 1.7 x 10 7 units/ml) of lysozyme as per supplier's instructions 1. Sample Preparation NOTE: For DNA isolation from blood containing Gram positive bacterial pathogens, please see Appendix A for Sample Preparation. a.

Appendix A Notes prior to use: Prepare a 400 mg/ml stock solution (approximately 1.7 x 10 7 units/ml) of lysozyme as per supplier's instructions. Sample Preparation for Blood Containing Gram Positive Bacterial Pathogens a. Add 20 L of Lysozyme to a microcentrifuge tube, and transfer 20 L - 200 L of blood sample to the tube containing Lysozyme b. Mix well by vortexing, and incubate at 37 º C for 1 hour. (Note: 0.5 to 2 hours incubation time can be used depending on the bacterial strain being lysed). c. After incubation, add 20 L of Proteinase K (vortex before use) to the tube and proceed to Step 1c. Troubleshooting Guide Problem Possible Cause Solution and Explanation Magnetic beads were accidently pipetted up with the supernatant. The yield of genomic DNA is low DNA does not perform well in downstream applications. RNA is present in eluted DNA. The pipette tip was placed too close to the magnetic beads while pipetting Incomplete lysis of cells Amount of magnetic beads added was not sufficient DNA was not washed with 70% ethanol Ethanol carryover RNA is coeluted with the DNA. Return the magnetic beads and the supernatant back into the sample well. Mix well, and place the plate back onto the magnetic separation plate for the specified time. Carefully remove the supernatant without touching the magnetic beads. Ensure that correct volume of Lysis Buffer B was added to blood sample. Also increase incubation time up to 15 minutes at 55 C. Ensure that the magnetic bead suspension is mixed well prior to use to avoid any inconsistency in DNA isolation. Traces of salt from the binding step may remain in the sample if the magnetic beads are not washed with 70% ethanol. Salt may interfere with downstream applications, and thus must be washed from the magnetic beads. Ensure that the drying step after the 70% ethanol wash steps is performed, in order to remove traces of ethanol prior to elution. Ethanol is known to interfere with many downstream applications. Carry out a digestion with RNase A on the elution if the RNA present will interfere with downstream applications. Refer to manufacturer s instructions regarding amount of enzyme to use, optimal incubation time and temperature. 5
